Answer:
i)salt
Explanation:
NaCl is a neutral salt formed by reacting a strong acid HCl and a strong base NaOH. It is also ionic in nature.
It is also called common salt or table salt as it is used as edible in daily our life.
Because a solubility is calculated for saturated solutions we can write:
36.3 g NaCl ---100g water
x g NaCl ---- 300.0 g water
x=36.3*300/100=108.9 g NaCl
The sodium ion becomes hydrated. when sodium chloride dissolves in water, the sodium and chloride ions and the polar water molecules are strongly attracted to one another by ion-dipole interactions
